Mark Lacey 43775e817d Disallow some implicit pointer conversions in autoclosures. ...

Disallow implicit conversion or arguments from Array, String, and
InOut (formed by &) to pointer types if the argument is for an
@autoclosure parameter.

These conversions were really only intended to be used for C/ObjC
interop, and in some contexts like autoclosures they are not safe.
